What is the difference between the zinc plated color guide and the profiled steel sheet?
- Because the original plate is very thin, the quality of the anticorrosive coating directly affects the service life of the profiled steel sheet. In order to meet the requirements of processing and rust prevention, the coated steel plate shall be examined in accordance with the relevant provisions. Under normal circumstances, thin steel plate can also be used according to the requirements, after pressing type, and then coated with anti rust paint, or use stainless steel sheet, the original plate.Profiled steel sheet used in industrial plants, housing panels, wall panels, in the absence of general insulation requirements, steel per square meter of about 5~11 kilograms. Insulation requirements, availability of mineral wool board, glass wool, foam and other insulation materials. The profiled steel plate and the concrete are combined into a composite floor board, and the wooden formwork can be omitted, and the utility model can be used as a load-bearing structure. At the same time to strengthen the binding force of steel sheet and concrete, should be pre welding studs in steel plate or pressing two-way stiffeners
What is the hardness of the wear-resistant steel plate?
- WZB-NM500 is the production of Wugang is more than 450 hardness of HB class can be used welding of high strength wear-resistant steel structure, the manufacturing equipment is suitable for use in high wear, high impact situations, but also can be used as high strength structural steel yield strength more than 700MPa. His hardness can reach about HV1300.s
How to choose welding method for welding different plate and thick steel plate?
- How to choose welding method for welding different plate and thick steel plate?:It depends on what process you use welding: manual arc welding, thick plate side should do thinner processing, become 12 thick, that is, a transition ramp, 15 degrees can be reached, two plates corresponding to the edge of the same thickness. V shaped groove, single side 30 meter, V shape 60 degrees. Clearance 2, blunt edge 1-2 can. Submerged arc welding, the plate can be assembled after thinning, without beveling.s
